Since the sink drain is now probably in the wall, and a new trap will have to be located below grade and stubbed out under the tub or shower, you are probably looking at a new floor. You didn't mention if this was slab, or upper story. Since we can't see where all the pipes are in the walls now, it is hard to guestimate. There is quite a bit of work here. It certainly can be done.

This is a 2nd floor bathroom. i feel i can re do the floor myself after all is said and done.
I would like to try and do the plumbing myself, but i think i'll leave that to the pro's.
i'll probably save money using a plumber!

For all you plumbers out there, if i have the floor ripped up to expose the sub-floor,
and the sinks and tub already ripped out, how long (roughly) should it take someone
to re-route the pipes assuming it's a middle of the road job as far as complexity is concerned?

Lastly, what's the average hourly $ rate i should expect to pay for this?

Without knowing where the pipes currently run, you can't say. You might have to either take off the subfloor, or remove the ceiling below. Safer to remove the ceiling since you can't fall through that - gravity...

Depending on which way the joists go, and where the current drain pipes are, you might need to run the line below the ceiling to obtain the proper slope. Also, there is a limit on where and how big you can cut holes in joists.

You really can't tell until you know all of the variables.

FWIW, when I had a tub relocated and a toilet moved, it cost me about $1400 but they didn't have to run all new stuff, only moved some and ran new water lines. I installed the toilet flange once I finished the floor and the shutoffs and drain once the vanity was installed.

What these pros are trying to gently tell you is that there is no way to give even a ballpark guess without physically examining the job. There are just too many variables that can come into play. Of course it might be quite simple, but it very well could be a fairly major (aka "expensive") job, and it is one you would certainly want done right. Therefore, it would be my advise to call two or three local plumbing contractors to give you an estimate on the job. You can discuss with them how much of the job you can do and how that would affect the cost.

Thanks to all. Although a bit vague, this actually helps out a lot.
At least I know it's possible and since I plan on getting it done by
a contractor anyway, the next obvious step is to get the quotes.

I'll keep you all posted, and i'm sure i'll have plenty more questions
throughout the next couple months.

Your main question is "How Much?". Your second question is "Can I Do Some or How Much Of This?"

Answer the various Q's posed to you, and if you do not insist that now you deserve to have your main Question answered, you'll do fine here. You'll learn a lot fast. It's really easy; later you'll admit that the information asked of you was totally necessary, and that you needed to know it yourself.

Re-reading the questions that were implicitly asked by other posts above, I'll rephrase them for you.
-- Which way do the joists go?
-- Where is the "stack"? That is the main drain going down to the lower level and then out to the street.

Answer these two questions slowly and carefully, so that it becomes clear to all who read the answers how the physical space is laid out. Diagrams help. A lot. With no diagram, there WILL be more questions.

It's numbskull-simple once you know that this is important stuff to spell out for experienced people to take into consideration. It's in your best interest to know at least what is important to specify. If you bring someone in to your space and they get the impression that you don't even know that a joist might be something important, you might be opening yourself up to a real big emotional rollercoaster ride when they 1. lowball the estimate, 2. start the job and 3. then start saying, "now that we have uncovered the following... we now know we have to do something additional here ..."

I haven't moved into the house yet so I am unable to answer these 2
questions. I will follow up when I rip the floor up after I move in.

I used to have a job doing home improvemets for a few years, so I'm not
diving in blindly. More specifically, I tore a bathroom floor up before and
we ran into a lot of hurdles. However, we did not move any of the fixtures
which is why I was unsure if it could be done using the same drains.

My questions, so far, were answered.
can it be done - yes
how long will it take - depends on layout and existing joists and piping
how much - it varies but someone here paid $1400 for light modifications
i understand that may not be what i pay becasue every situation
is different.
